I have been seriously bitten by this track stuff and need to go faster! I lowered my car and it's scrapping everything as is, but my car isn't driven daily anymore so I'm thinking about going with a GT3 bodykit (preferably the 2010 conversion). here's the thing... I love how stealthy my car is! It's totally stock on the exterior but is worked to the max under the skin. I like not being all flashy, but if the body kit will allow me to attain higher speeds (more grip) in the corners I would love to do it! I currently am running toyo r888 ( r compound tires ) and seem to only find there limits after about 10 laps or so. What do you think?

 

I don't have anybody work on my car, and I like the stock/stealth look (if you can have a stealth look on a Porsche). I find that I have no problems holding my car were I need to as it is. I have seen many GT3 splitters on the track, and never have to worry about it. If you want more speed, try the Hoosier R6's. They will give you better braking, and cornering...this will increase your straight away speed, as you can carry more speed in the corners and brake later then you can with R888. Also the grip limits are much higher on the Hoosiers, however when you do find the limits, it is a quick transition to the other side!

 

Forget about going for an Aerokit for aerodynamics reason... If youre going to do it, do it because you like it, just like me It's not even going to make a 1 second difference.

I agree with NorthVan, you should give Hoosiers a chance. But beware that they are more expensive, heat-cycle out faster, and you don't get much feedback when they're at the limit.

Do you have a LWFW on your car? It helps with quicker acceleration.

 

Also an LSD if you don't have one.

 

I have 1

 

Go with the kit, just looks cooler coming up in the rear view mirror

 

If you want to go faster, hire a pro coach. It's really that simple. Getting propper instruction is the best mod there is.

 

How would a body kit help in corners? Are you carrying enough speed, in the corner, to create any reasonable downforce? Seriously, I don't know - just wondering...

 

aero car is a much more than just fancy bumper and a wing. proper aero race car has full cage, very stiff springs and aero elements are way bigger than GT3 ones. suspension tuning in aero car is also different.

what people do is to put cup car parts on - drop doors and put on cup ones, put in recaro seats, cup wing, cup front splitter, etc.
it all gets quite crazy and expensive. I would say - run your car as it is and if you think you want to be serious - spend some $$$K on a dedicated race gt3s class car - you can find one in $50K budget - an older one based on rs america model or similar.

really the most difficult problem with all this modding stuff is to know where to stop.

or, alternatively - you can continue on stripping your car down similar to this spec - http://www.996specracing.com/The_Spec.html

 

It would have to be a sweeping bend were were speeds are up around 80-100+mph. At Sebring I have 1 turn like that.

I see guys at the track all the time with loads of mods for the car. They have the best of everything...car looks like it's ready for the 24hr race. My car is stock except for pads, alignment and a Tubi muffler....I get lots of point by's at the track. LOL

 

Got to love it when that happens, just a C2S cruising along.

 

+1 on what mdrums said. Get professional instruction.

With most 911's it is much, much, much easier to improve the driver than the car.

(but I understand mods can be a lot of fun too!)

For most people, the body kit is the last item that will improve track performance. Some other items noted in the responses would come well before the body kit. But the reality is that for the overwhelming number of people, improvements in the wetware (um, that would be you) would yield far greater results. Time, lots of time spent with an instructor, will have the best ROI for your track performance, enjoyment and safety.
OTOH, if you go with the bodykit, others seeing themselves pulling away from you in their rear-view mirror will feel rather studly.
All kidding aside, it does make the car look really nice. But that's about all.
